Arduino Nano 33 BLE Sense Rev2 with Headers [ABX00070] – AI Microcontroller with Sensors, Bluetooth, for Wearables, Gesture & Voice Recognition

If you are on budget and want to get the most from every cent spent then get this board. Many tutorials, courses and books are covering all aspects of this board. Perfect kick start to the world of timyML. If you are willing to spend and invest more then a nice companion for this board is something from sparkfun ML family, see the right side of the picture attached.

This is my go-to board for sensor-based projects. It replaces the previous (no Rev2) board with more capable sesnors.

My use case is a lot different from other people. I bought this specifically to do some BLE development because I'm a huge fan of the NRF52840 chipset. If you've done Bluetooth or BLE development you know how bad the stacks are on Linux and Windows. The Nordic chipsets solve this issue, but of course the hardware is only as good as its software abstraction layers. I haven't used Arduino in a long time and I expected the libraries to be much better than they are. If you're using the built-in sensors only it's fine, but if you're digging in deeper trying to make a BLE peripheral or controller (just plain Bluetooth low energy without any sensors) then it's going to cause a headache because the documentation for ArduinoBLE.h is a total disaster and there really aren't that many examples available. That said, if you can figure out how to get it to work I think the abstraction layer is probably more intuitive to use than the Nordic SDK, but since it's barely supported and nobody else seems to use it for this purpose, examples are severely lacking. Even for basic everyday things like trying to connect it to your smartwatch to read the heart rate service, for example. If you're looking to use this for its sensors then I would recommend it but if you're looking for BLE development you're better off with something else entirely.
